Analysis

Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine.

Pumped storage hydropower is used as a long duration energy storage mechanism – storing energy during periods of low demand and releasing it during peak demand. This makes it a critical tool for grid stability and energy storage.
